HOSECOUPLINGI SPECIFICATION forming part of Letters Patent N 0. 721,985,dated March 3, 1903.

Application filed March 29, 1902.

To all whom it 7nd, concern.-

Be it known that I, AB SALOM B. WELLS, a citizen of the United States,residing at Washington, in the District of Columbia, have invented a newand useful Hose-Coupling, of which the following is a specification.

This invention relates to hose-couplings, and has for its object toprovide simple and effective means for detachably connecting ahose-section to a pipe or nozzle and to dispense with the usualscrew-threaded connection between the hose-section and the nozzle.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a perspective View of a hose-couplingembodying the features of the present invention. Fig. 2 is alongitudinal sectional view thereof. Fig. 3 is a detail sectional viewtaken through the end of the hose-section to illustrate the manner ofconnecting the swinging bail thereto. Fig. 4 is a detail view of thenozzle.

Like characters of reference designate corresponding parts in all thefigures of the drawlngs.

As illustrated in the accompanying drawings, the coupling is made up oftwo tubular members, (designated 1 and 3, respectively.) The relativelyfixed or body member or nozzle proper, 1, is'designed to have its rearend fitted within the hose-section 3 and is provided with anintermediate external annular shoulder 4 to abut against the end of thehosesection and limit the inward movement of the fixed body member ornozzle.

Although the rigid member 1 has been shown with an enlargedinteriorlyscrewthreaded coupling 10 at its outer end, which is designedto receive tips of different sizes and shapes, it will of course beunderstood that any form of coupling may be employed at this point.

For connecting the rigid member or nozzle 1 to the hose-pipe section 3the forward end Serial No. 100,550. (No model.)

1 of the latter is provided with a metallic collar or band 11, having aninwardly-directed annular flange 12 to overlap the outer end of thehose-section. A substantially U-shaped bail 13 diametrically straddlesthe band or collar 11 and is swung thereto by means of pivot-pins14,Which pierce the ends of the hail, the collar or band,and theadjacent sides of the hose-section, so that in addition to formingpivots for the hail the pins 14 also serve to hold the collar or band tothe hose-section. The nozzle or rigid member 1 is provided with alaterally-directed external shoulder or projection 15, lying between theannular shoulder 4 and the outer end of the member and adapted to havethe bail l3 forced over the shoulder and engaged with the forward sidethereof, so as to. hold the annular shoulder 4 in snug engagement withthe end of the hose section, and thereby form a strong and durable andalso detachable connection between the nozzle and the hose-section. Itwill of course be understood that the shoulder 15 is located at apredetermined distance from the shoulder 4, substantially correspondingto the length of the bail 13, so that it is necessary to employconsiderable force to snap or press the bail into engagement with theshoulder 15 in order that a tight and effective connection may be hadbetween the nozzle and the hose. the front end of the shoulder or keeperis abrupt, as it is disposed at substantially right angles to thenozzle, whereby it requires con- It will be noted that siderable forceto disengage the bail therefrom. The nozzle may be readily detached fromthe hose by forcing the pivotal bail out of engagement with the shoulder15.

There are several very important features embodied in the coupling orconnection between the hose and the nozzle. One of these featuresresides in the fact that the metallic nozzle member is smooth and ofconsiderable length between the inner end of the member and the shoulder4, whereby the nozzle may be forced into the flexible hose, and it istherefore not necessary to rotate the nozzle, as in the ordinaryscrew-threaded form of coupling. In addition to this in forcing thenozsame and cause it to more firmly grip the nozzle and, in effect, forma continuous washer from the rear or inner extremity of the nozzle tothe shoulder 4. Another feature is brought about by the fact that theflange 12 of the band 11 is of a length less than the thickness of thehose, so as to terminate short.

of the opening formed in the hose, whereby the inner exposed edge of theflexible hose around the opening is compressed between the band 11 andthe inserted portion of the nozzle, and thereby acts as a washer to forma water-tight joint between the shoulder 4 and the flange 12 of theband.

From the foregoing description it is apparent that the inventionprovides very simple and at the same time very effective means forconnecting a nozzle or any ordinary pipe to a hose, and said connectioncan be conveniently manipulated to facilitate the application andremoval of the nozzle. Practical experiment has demonstrated that awatertight joint is produced which will stand the ordinary city pressurewithout leaking.

What I claim isl. The combination with a flexible hose, of a rigidtubular member fitted snugly within and projected from one end of thehose, a stiff band rigidly fitted to one end of the hose and providedwith a flange which embraces the end wall of the hose, but is of alength less than the thickness of the hose, so as to terminate short ofthe opening formed in the hose, and means carried by the band forconnecting the hose to the exposed end of the rigid member.

2. The combination with a flexible hose, of a rigid tubular memberfitted snugly within and projected from one end of the hose, with aportion bearing against said end of the hose to limit the insertion ofthe member, a lateral projection upon the rigid member in front of thehose, and a bail straddling the hose with its opposite terminals pivotedthereto and its closed free end frictionally embracing the projection.

3. The combination with a flexible hose-section, of a rigid tubularmember fitted snugly within and projected from one end of thehosesection, and provided with a shoulder hearing against said end ofthe hose to limit the insertion of the member, that portion of the hoseextending from the shoulder to the inner end of the rigid member beingcompressed upon the latter and forming a continuous washer, a rigid bandsnugly embracing the end of the hose-section contiguous to the shoulder,and means carried by the band for engaging with the exposed end of therigid member and holding the end of the hose-section in contact with theshoulder.

4. The combination with a flexible hose, of a collar or band embracingthe same, a swinging bail embracing the collar, pivot-pins connectingthe bail to the collar and also connecting the collar to the hose, and anozzle fitted snugly within the hose and having a keeper disposed forengagement by the bail to detachably connect the member with the hose.

6. The combination with a flexible hose-section, of a rigid tubularmember fitted snugly within and projected from one end of thehosesection, means for limiting the insertion of the said member withinthe hose, that portion of the hose traversed by the rigid member beingcompressed upon the latter and forming a continuous washer, a rigid bandembracing the forward end of the hose-section and secured thereto andprovided with an inwardly-bent flange which fits against the extremityof the hose, said flange being of a length less than the thickness ofthe hose so as to terminate short of the opening formed in the hose forthe purpose described, and means for connecting the hose to the exposedend of the rigid member.

7. A hose-coupling, comprising a flexible hose-section, a tubularmetallic member having one end snugly fitted within the hose andprovided with an external peripheral shoulder lying against the end ofthe hose a stiff band snugly embracing the end of the hose and having aninner peripheral flange lying against the end of the hose between thelatter and the shoulder of the tubular metallic member and terminatedshort of the inner wall of the hose, and means extending between thetubular metallic member and the band for detachably fastening thetubular member to the hose-section.

8. The combination of a flexible hose-section, having a metallic bandembracing one end portion thereof and provided with an inner annularflange lying against the extremity of the hose and terminated short ofthe inner wall thereof, a nozzle having its rear end snugly fittedwithin the hose and provided with an external annular shoulder lyingagainst the end of the hose, a shoulder projected laterally from thenozzle with its forward end disposed at substantially right angles tothe nozzle, and aswinging bail straddling the end of the hose, with itsopposite ends pivotally connected to the band and its free enddetachably engaging the abrupt shoulder on the nozzle.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature inthe presence of two witnesses.
